Does NetDuma or DumaOS have an online demo/router emulator user interface like the other router manufacturers, e.g. Asus,TP-Link, D-Link, Mikrotik etc.? I think not many people understand just how different interfaces and feature sets can be while shopping for a router. It also makes it harder to give recommendations because each person's use case is different. With an online demo you can just point! It would show all or most of the features and does not rely on user created content which may not even be available for new devices, precisely when it a device is most anticipated, or may be missing features that a potential customer could want. Also, does NetDuma or XR500 DumaOS support: OpenVPN client (especially with UDP and certificates) WAN failover USB LTE modem? Thanks for your help! If it does not have any of the above, I recommend them as feature requests.
